Site characteristics
The Ngoyla Wildlife Reserve is situated in southeastern Cameroon. Located between Nki National Park and Dja Biosphere Reserve, the site is also part of the TRIDOM conservation landscape (WWF). In 2014, the government of Cameroon, in collaboration with WWF and the World Bank, created the reserve. Along with the reserve, five new forestry concessions were created, covering nearly 500,000 ha in the same forest block (Ngoyla Mintom forest block), on the lands belonging to the indigenous Baka and Bantu peoples (FPP 2019). Mammal species inhabiting the site include forest elephants, gorillas, chimpanzees, mandrills, buffalos, bongos, sitatungas, panthers, duikers, water chevrotains; more than 280 bird species and 230 fish species are also found at the site (WWF).
